There are companies who make artificial nails for men. These nails tend to be a bit wider than those for women, but otherwise, they are just like the glue on nails women use.
Though this may seem a bit odd at first, there are actually a few reasons men might seek out fake or glue on nails. The first is for men trying to stop from biting their nails. Often having tough plastic can help because it is harder and does not taste good at all. Another reason is cross dressing. Cross dressing is when a male dresses like a woman, or a woman dresses like a man.
